All releases of pipemeter

Release Notes: This release is only known to be relevant for
people using older compilers and FreeBSD. The
copyright messages were updated. A patch to make
pipemeter compile cleanly on older versions of gcc
was applied. The pkgpipemeter.sh script was fixed
to create tags in the tags directory.

Release Notes: The code was changed to use autoconf more
effectively. strtoll() is used when OFF_T is
bigger than a long. The second item makes it so
that numbers larger than 2^^31 can be passed into
the --size/-s parameter.

Release Notes: In this version, rate-only shows elapsed time, the progress bar
shows elapsed time at the very end, there are fixes for errno
handling and EINTR-less platforms, the adaptive block sizing
was fixed in rate-only mode, and the adaptive block sizing
aligns sizes along 8 bytes.
